+- Updated detach_disks.sh to not use predictable temporary file
+  names. (bsc#1182777)
+- Made for the following changes for bsc#1182816:
+  * Updated s390-tools-sles15sp3-Format-devices-in-parallel.patch to
+    change all instances of the progress bar from printing "#" to
+    printing the process number of the DASD volume being formatted.
+  * Updated s390-tools-sles15sp3-Implement-Y-yast_mode.patch to print
+    out the numbder of cylinders in a device, as was done in the
+    prior versions of this patch, but was missed when modifying it
+    for SLES15 SP3.
+  * Added s390-tools-sles15sp3-check-return-code-from-util_file_read_l.patch
+    because otherwise a warning message from dasdfmt is being generated
+    that could interfere with YaST properly processing the progress
+    of the formatting process.
